Definitions

  • the present invention relates to a method for detecting articles which are carried by a conveyor, and more particularly to a method for detecting square shaped articles which are formed with a stepped portion.
  • Some square-shaped containers for containing milk, juice, etc. as shown in Figure 1 are formed such that the edge a is folded back along the upper end of the container A.
  • the folded-back edge portion a sticks out over the other portions a' and all as shown in Figure 2.
  • the object of the present invention is to provide a method for detecting articles or containers carried by a conveyor even when the containers are fed contiguously, i.e. one after another.
  • the inventor noted and utilized the fact that the stepped portion is formed at the corner of the article and designed a method for reliably detecting the article by projecting the light from a diagonal direction to the space formed by the aforementioned stepped portions of the contiguous articles.
  • articles such as containers A, are carried by a conveyor C.
  • a photoelectric sensor D which uses a phototube is provided by the side of the conveyor C.
  • the optical sensor axis of the light projected from the photoelectric sensor D is arranged to intersect the upper corner of the article A diagonally as shown in the Figure.
  • this photoelectric sensor D reliably detects the stepped portion formed at the upper corner of the article, this is, a gap X Shown in Figure 3. Also, even when the articles are fed one after another in a form to push and to be pushed one by one as shown in Figure 3, the photoelectric sensor D does not fail to detect the gap X formed.
  • the gap X is formed by the stepped portion of the articles next to each other at the upper corner of the article.
  • the photoelectric tube used is of an optical fiber type that is capable of detecting even such a small gap.
  • the numeral 1 is a photoelectric tube and 2 denotes the optical fibers.
  • This embodiment illustrates a case wherein the front end portion of the article is detected by the photoelectric sensor. which uses the phototube. However, it May be arranged to detect the rear end portion of the article by the photoelectric sensor.
  • the essential point here is that the stepped portion formed at the corner of the article is detected by the photoelectric sensor using the phototube. Furthermore, in the embodiment shown here, the stepped portion is formed at the upper corner of the article, but the method of this invention still applies also to cases wherein the stepped portion is formed at the lower corner of the article.
  • the position detection method provided by this invention the positional adjustment of a pair of photoelectric tubes can readily be carried out.
  • the sizes of the articles do not cause any trouble when adjusting the position of the photoelectric sensor, and reliable detection performance can be obtained.
